Abstract

Abstract

Titanium is widely used in national defense and civil fields due to its various excellent properties. In order to continuously produce large coils of heavy titanium strip with high efficiency and low cost, conventional hot tandem rolling production lines for co-linear production of titanium, titanium alloys and steel are the development trend. For steel-titanium co-linear rolling of hot-rolled titanium coil, reheating is the key step. Based on the 1 450 mm hot strip rolling line, in order to solve the problems of low efficiency and high energy consumption of titanium coils, a solid model of the billet heating furnace through ANSYS finite element had been developed to analyze the fluid conditions in the furnace through Fluent simulation calculation. The temperature distribution of titanium slab at different stages in the reheating furnace under optimal air-fuel ratio had been studied. The technology of synchronously reheating titanium billets in large billet reheating furnaces had been well established from this research and successfully been used to achieve efficient and high-quality production of titanium coils.
